Scales & Modes

What is a Scale?

A scale is a sequence of notes following a specific pattern of intervals (whole and half steps). The pattern repeats each octave, giving every scale its characteristic sound. Scales are the raw material for melody and the foundation of harmony.

Major Scale

Formula: W W H W W W H — W = whole step (2 semitones), H = half step (1 semitone). The major scale sounds bright and happy.

Natural Minor Scale

Formula: W H W W H W W. The natural minor scale sounds darker and sadder than major — the lowered 3rd, 6th, and 7th degrees create the characteristic sound.

The 7 Modes

Modes are scales built on each degree of the major scale. Each mode has a unique character from its distinct pattern of half and whole steps.

Pentatonic Scale

The pentatonic scale removes the 4th and 7th degrees from the major scale, leaving 5 notes. It avoids all semitone clashes, making it sound universally smooth. Used everywhere in rock, blues, pop, and folk.
